Camp Century was part of a top secret US plan to deploy nuclear weapons beneath Greenland's ice sheet. 50 years after it was abandoned, scientists say a warming Arctic may expose the waste left behind.

Global warming has profound effects on our planet, including melting Earth’s immense ice sheets. A new study from NASA reveals an unexpected result of all that ice melting: It’s moving the axis of rotation of the entire planet.

Scientists working in Greenland are looking for tiny clues to help fill in the big picture about the fate of the island's giant ice pack. They're using cutting edge technology to track minute changes that could help predict what a warmer future might hold for Greenland and the rest of the world.

About a decade ago, several of Greenland's biggest glaciers suddenly began melting. A decade later, two groups of scientists are trying to unlock the secrets behind a scientific mystery story with potentially big consequences for the future of the island's rapidly-melting ice sheet.

Greenland is melting fast, and that's bad news for sea level rise and other impacts of climate change. But The World's Ari Daniel, on assignment with scientists studying a rapidly melting Greenland glacier, says all that bad news doesn't make the world's biggest island any less of a wondrous place.

When it comes to global warming, it appears that the greatest rate of warming is happening at the poles. That conclusion was strengthened recently by a couple of new studies focusing on the melting of the Greenland ice sheet. They each looked at different measurements, but both agreed that the impacts of global warming on the ice are underestimated.

Science fiction has long envisioned "tractor" beams that could grab and move physical objects using a laser or other stream of energy. Now scientists have created one, at least on a small scale. And we have some advice if you use heat in the winter. Most Brits, and many of us, apparently don't know how to use our thermostats. Also, Chinese officials go on a worldwide corruption hunt, in today's Global Scan.

Greenland is home to a huge chunk of the Earth's frozen water. And every winter that ice is covered with snow, usually white snow that reflects sunlight back into space. But new information suggests that pollution and a warming climate are making that snow much darker — and consequently making it melt much faster. That story and more in today's Global Scan.

If climate change goes as predicted, it is going to get harder and harder to find cities with the weather and infrastructure to successfully host the winter Olympics. And as winter retreats around the world, will people still even care about the winter games?

40 years ago, a U.S. military plane carrying nuclear weapons crashed in Greenland. A BBC investigation has found that one of the nukes was unaccounted for after the crash. The BBC's Security Correspondent Gordon Corera has details.
